Ingredients for Your Creamy Creation
Let's gather the components for this show-stopping dish.
For the Savory Meatballs:
Ground Beef: 1 lb (about 500g) of lean ground beef. A mix with pork also works well for extra flavour.
Breadcrumbs: ½ cup of Panko or regular breadcrumbs.
Large Egg: To bind the meatballs together.
Worcestershire Sauce: 1 tablespoon, for a savory, umami kick.
Seasoning: Salt and freshly cracked black pepper.
For the Creamy French Onion Sauce:
Onions: 3 large yellow or sweet onions, thinly sliced.
Butter: 3 tablespoons of unsalted butter.
Garlic: 3-4 cloves, minced.
Beef Broth: 2 cups of good-quality beef broth.
Fresh Thyme: 3-4 sprigs, or ½ teaspoon of dried thyme.
Heavy Cream: ½ cup, for that luscious, creamy finish.
Gruyère Cheese: 1 cup, shredded. This is the classic French onion soup cheese for its nutty flavour and perfect melting quality. Substitution: A good quality Swiss, Emmental, or even a sharp white cheddar cheese will also be delicious.
How to Make French Onion Meatballs
1. Form the Meatballs: In a medium bowl, gently combine the ground beef, breadcrumbs, egg, Worcestershire sauce, salt, and pepper. Be careful not to overmix, as this can make the meatballs tough. Roll the mixture into 1-inch balls.
2. Brown the Meatballs: In a large, oven-safe skillet (a cast-iron skillet is perfect here) over medium-high heat, add a drizzle of oil. Brown the meatballs on all sides. You don’t need to cook them through at this stage. Once browned, remove them from the skillet and set them aside.
3. Caramelize the Onions: Reduce the heat to medium-low. In the same skillet, melt the butter. Add the thinly sliced onions and a pinch of salt. Cook slowly, stirring occasionally, for 20-30 minutes. This is the most important step! Be patient and allow the onions to become deeply golden, soft, and sweet.
4. Build the Sauce: Once the onions are caramelized, add the minced garlic and thyme sprigs and cook for another minute until fragrant. Pour in the beef broth, scraping up any browned bits from the bottom of the pan—this is where the flavour is!
5. Simmer and Combine: Bring the sauce to a gentle simmer. Return the browned meatballs to the skillet, nestling them into the onion sauce. Cover, reduce the heat to low, and let everything simmer for 15-20 minutes, or until the meatballs are cooked through.
6. Add the Creamy Bliss: Uncover the skillet and remove the thyme sprigs. Stir in the heavy cream until the sauce is smooth and luxurious.
7. Top with Cheese and Broil: Preheat your broiler. Sprinkle the shredded Gruyère cheese evenly over the meatballs and sauce. Place the skillet under the broiler for 2-4 minutes, watching it carefully, until the cheese is completely melted, bubbly, and beautifully golden-brown.
8. Rest and Serve: Carefully remove the skillet from the oven. Let it rest for a few minutes before serving hot.
Make-Ahead & Storage Tips
Make-Ahead: You can prepare the meatballs and the sauce (up to the point before adding the cream) a day in advance. Store them separately in the refrigerator. When ready, simply heat the sauce, add the meatballs to simmer, and finish with the cream and cheese.
Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days.
Variations
Different Meats: Try this recipe with ground chicken, turkey, or a veal-pork blend.
Add Mushrooms: Sauté sliced mushrooms along with the onions for an extra layer of earthy flavour.
A Splash of Something Extra: For a more traditional French onion flavour, you can deglaze the pan with a splash of dry white wine or brandy before adding the beef broth.
Expert Tips for Perfection
Patience is a Virtue: The secret to incredible French onion flavour is the slow caramelization of the onions. Don’t rush this step! Low and slow is the way to go.
Don't Overwork the Meat: Mix the meatball ingredients only until they are just combined. This ensures they will be tender and juicy.
Use an Oven-Safe Skillet: A cast-iron or other oven-safe skillet makes this a true one-pan meal, which is fantastic for minimizing cleanup.
Shred Your Own Cheese: Pre-shredded cheese is often coated with powders that prevent it from melting smoothly.
Grating a block of Gruyère yourself will give you the best, gooiest cheese pull.
French Onion Meatball FAQs
Can I make this dish without an oven-safe skillet? Yes! Simply follow the steps on the stovetop. Once you’ve added the cream, transfer the entire mixture to a baking dish, top with cheese, and then place it under the broiler.
My sauce seems a little thin. How can I thicken it? If you prefer a thicker sauce, you can create a small slurry by mixing 1 tablespoon of cornstarch with 2 tablespoons of cold water. Slowly whisk this mixture into the simmering sauce before adding the cream and let it cook for a minute or two until thickened.
What are the best onions to use for caramelizing? Yellow onions are the workhorse for caramelizing, as they have a great balance of astringency and sugar. Sweet onions (like Vidalia) also work beautifully and will result in an even sweeter final sauce.
